Display Device Having Gap Width Measuring Device Between Panels and Control Method Therefor

2. The display device according to claim 1, wherein the connecting element is a joint, via which the panels can be pivoted between the aligned position and a folded position.

3. The display device according to claim 1, wherein the connecting element is a coupling via which the panels are detachably connected.

4. The display device according to claim 1, wherein the measuring device is configured to continuously determine said gap width during operation of the display device.

5. The display device according to claim 1, wherein the measuring device comprises at least two sensors spaced from one another in the longitudinal extension direction of the gap, the first of which measures a first width of the gap at the level of the first sensor, and the second of which measures a second width of the gap at the level of the second sensor, wherein the measuring device is configured to determine the gap width at the level of each row on the basis of the measured first and second widths.

6. The display device according to claim 1, wherein the display device comprises a third panel which can be aligned with the first panel to form a further gap, wherein the measuring device is configured to also determine a width of the further gap, and wherein the driver is configured to control said luminous elements also as a function of the determined width of the further gap.

8. The panel according to claim 7, wherein the measuring device comprises at least a sensor which is integrated into a peripheral side of the panel facing the gap.

9. The panel according to claim 7, wherein the panel is configured to receive a width of a gap between the panel and a further panel from the further panel and to control its luminous elements as a function of the received gap width.

10. The panel according to claim 7, wherein the panel can be aligned with a third panel to form a further gap, wherein the measuring device is configured to also determine a width of the further gap, and wherein the driver is configured to control said luminous elements also as a function of the determined width of the further gap.

12. The method according to claim 11, wherein said determining and said controlling are carried out repeatedly during operation of the display device.

13. The method according to claim 11, wherein the display device comprises a third panel which can be aligned with the first panel to form a further gap, characterized in that in said determining, a width of the further gap is determined, and in said controlling, said luminous elements are also controlled as a function of the determined width of the further gap.
